Question 920335
The current (I) in a wire varies directly as the voltage (v) and inversely as the resistance (r).
Ohm's law: I = v/r
 If the current is 27.5 amps when the voltage is 110 volts and the resistance is 4 ohms,
:
 find the current when the voltage is 120 volts and the resistance is 12 ohms. 
I = {{{120/12}}}
I = 10 amps
